I didn't actually meet Hollis in person, but I met his friend John and had no trouble finding it. The place was in a very colorful location of the city. It was convenient as well due to the proximity of the Sky Train. Although the place is relatively clean, the photos definitely make the apartment look much more posh and elaborate than it actually is. However, it is a good deal if you want a reasonably-priced centrally located place. I'd stay there again,
One thing to mention is that the area brings out an array of characters. I particularly found it interesting to see the underbelly of Bangkok nightlife and I didn't feel unsafe at all. I suggest you do your own research about 'Nana' before you decide to book it.
